Not another why why why so many
i tested this for a bit- honestly.. i kinda like dropbox.com>than -- but the copy.com stuff definitely is feature rich.
I use OwnCloud, on a mini-itx server at home. Gives me 4.5TB of storage and if I want more I just put a new disk in. Privacy is very good because its in my house and all transport is over HTTPS.
Otherwise Copy isn't too bad, but its online offerings are limited.
Works very well for me. It even supports symlinks in your home directory. Just right click the file or folder and select "Make Link" the resulting icon is then dragged into your Copy folder and it just works. You can get a free extra 5 GB by signing up with this link: https://copy.com?r=aTrLih

It works fine with symlinks, good alternative to Ubuntu One, specially for that big amout of free storage. Here is my referral link https://copy.com?r=RS9B4K use it for signing up and get 20GB.
